The importance of moulting for growth in farmed shrimp is reviewed in relation to the physiological cycle, induction triggers, behavioural and compositional changes, elements for successful moulting and potential strategies for moulting management. Successful ecdysis is also dependent on pond water quality, health and nutritional status. The stages in the moulting cycle are as follows: premoult, the preparation period for moulting that comprises the longest period in the cycle and includes accumulation of nutrient reserves; post‐moult, short and crucial stage for shrimp recovery after moulting; and intermoult, when feeding is continuous and most of growth occurs. The ecdysis is very rapid and mainly dependent on suitable physiological status of individuals. Up to 10% of the whole shrimp moulting cycle may rely on body nutrient reserves, once feeding is decreased or ceased (premoult and post‐moult). Moulting is started by hormonal increments in haemolymph, 20‐hydroxyecdysone and methyl farnesoate, which are found similar in insects. Beyond health and nutrition, proper environmental conditions such as good water quality are essential for successful moulting, hardening of exoskeleton and rapid growth. Moulting prediction and management may result in significant feed savings in pond farming and potential effects of, for example, moon phases and stressors have to be further considered. The complex nature of moulting in shrimp, including different sorts of endocrine regulation and environmental stimuli, suggests it is difficult to be precisely controlled in farmed populations. Moulting physiology of shrimp is discussed in relation to some farming practices.

换成养殖虾的成虫：回顾

回顾了换羽对养殖虾生长的重要性，涉及生理周期，诱导诱因，行为和组成变化，成功换羽的要素以及换羽管理的潜在策略。成功的蜕皮还取决于池塘的水质，健康状况和营养状况。换羽周期的各个阶段如下：换羽前，换羽的准备期包括周期中最长的时间，并包括养分储备的积累；换羽后，短而关键的换羽期对虾的恢复阶段；和连续繁殖，当连续喂食且大部分生长发生时。蜕皮非常迅速，并且主要取决于个体的适当生理状态。在整个虾的换羽周期中，多达10％可能依赖于人体的营养储备，一旦减少或停止饲喂（产前和产后）。蜕皮始于血淋巴，20-羟基蜕皮激素和法尼酸甲酯的荷尔蒙增加，这在昆虫中也很相似。除了健康和营养外，适当的环境条件（如良好的水质）对于成功换羽，骨骼硬化和快速生长至关重要。换羽的预测和管理可能会大大减少池塘养殖中的饲料消耗，因此必须进一步考虑月相和压力源的潜在影响。虾换羽的复杂性，包括不同种类的内分泌调节和环境刺激，表明在养殖种群中很难对其进行精确控制。对虾的蜕皮生理与某些养殖方式进行了讨论。
